ISTJ or INFJ? Could I have changed?

[jnick1972]

For a long time I was positive that I was an INFJ, because I fit the type description so closely. A friend, not a pro, gave me the test out of a book, which I know isn't necessarily going to give the most accurate answer, but at the time I knew nothing about MBTI and was taking the test "just because." (I did, however, take it seriously and answer honestly). Afterward, I read many descriptions about INFJ's and was sure that was me. Several months ago, I tested as ISTJ. I have read many descriptions of ISTJ's and I seem to fit that type also. Both types seem to be an equally close fit to my personality. I don't match any of the other types, and the only things in question are the S/N and T/F. I'm most definitely and I and J.

I'm wondering if MBTI type can change in a person. If it can, perhaps that's the explanation. I saw some things in myself that I didn't like, things that were causing distress to me personally, and I willfully made some changes. That may make it seem as though I'm an INFJ by nature, but I have forced myself to behave as an ISTJ, and that's a possibility I've entertained. But I'm not so sure that's what happened. It may be that I behaved as an INFJ but finally gave myself permission to be my true self--an ISTJ.

How can I figure out my true type when I'm so close to both?

So back in the day, so to speak you merely read a description for INFJ out of a book and decided that was a match? Just trying to get your story right.

I would say if you recently tested as an ISTJ, you are more than likely an ISTJ. It is possible that some of your letters aren't as dominant, meaning you could be borderline N and borderline F. It's possible. You should try to take another test. Some/most of the tests online should tell you by percentage how strong each trait is and that should give you an idea if your middle two letters are truly borderline.

Last time I tested I was borderline S/N. My S is a little more dominant though, so I go with that.

you gotta learn the functions. that's really the only way to figure out your type.

[jnick1972]

I took the test from the book and the results showed me as INFJ. It was after that that I read the descriptions and figured that the test results were accurate (with zero training I felt comfortable making that assessment--yessh!). I didn't explore any other possible types at that time.

I took another test this morning and the results once again showed ISTJ, and I do believe that I'm close to borderline between S and N and T and F. I'm inclined to go with ISTJ, since that's what the results show.

What do you want to be?


Us ISTJs aren't that bad, despite what you've heard. Welcome aboard. lol

For real though, try to find a good description of each trait and then analyze yourself and see what fits you best, focusing on the middle two letters since it seems that's where your confusion is.

Maybe you don't have a "true type." Don't worry so much about trying to fit into a crude classification system. If I asked you if you were democrat or republican, and you had some views that fit both descriptions and some that probably (hopefully) fit neither, would you worry about who you are, or worry about the strength of the classification system instead?

What do you want to be

Hmm, tough choice. If I could, I'd probably want to be an ENFP. The ones I know seem like they're having fun all the time. Not that I could be an ENFP, even if my life depended on it...

I am indeed trying to learn the functions, but that'll take some time.

Maybe you don't have a "true type." Don't worry so much about trying to fit into a crude classification system. If I asked you if you were democrat or republican, and you had some views that fit both descriptions and some that probably (hopefully) fit neither, would you worry about who you are, or worry about the strength of the classification system instead?

If you asked my political party, I would probably attempt to go into a detailed explanation about that, because I wouldn't want anyone to think that I agree with all the views of that particular party. Anything that isn't precise, including definitions, bothers me. I'm working on that.

I do get your point, though.

ISTJs and INFJs are not very similar at all in my opinion. It should be easy to tell which one you have a stronger preference for by looking at the functions:

ISTJ - Si, Te, Fi, Ne
INFJ - Ni, Fe, Ti, Se

They don't have a single function in common. Should be easy. Don't over think it. Sometimes it is easier to look at the negative aspects of both to see which one fits you better.

o_O INFJ is literally the most different type you can get from ISTJ.

Please look at function usage...

INFJ -> NiFe TiSe NeFi TeSi
ISTJ -> SiTe FiNe SeTi FeNi

They're literally everything including shadows backwards!

Ask yourself... what do you have more Ni or Si... then Fe vs Te as sassa suggested. Have fun!
